This dataset contains the near-surface (nominally 3 m depth) temperature and salinity observations collected during the Subtropical Shelf Front Cruise (PD_2013_04) on board the research Vessel Puerto Deseado from 3 to 10 October 2013. 

A SeaBird Electronics SBE 21 thermosalinograph, which recorded every 30 seconds, was used throughout the cruise. Data records in physical units are reported in an ascii text file. The variables are presented in the following order, with missing values indicated by "-9.990e-29":

Julian Days 
Latitude [deg]
Longitude [deg]
Pressure [dbar]
Temperature [ITS-90, deg C]
Conductivity [S/m]
Salinity, Practical [PSU]
Sigma-t [kg/m^3]

Data were calibrated and quality controlled at the Servicio de Hidrografía Naval, Argentina (mcharo@hidro.gov.ar).
